Set in a world where The Joker is cured of his insanity and homicidal tendencies, The Joker, now known as “Jack,” sets about trying to right his wrongs. First he plans to reconcile with Harley Quinn, and then he’ll try to save the city from the one person who he thinks is truly Gotham City’s greatest villain: Batman!

Public support for Batman dwindles and Gotham City’s 99 percent rally around ex-Joker Jack Napier’s crusade to expose decades of corruption within the GCPD. A proposition inspires new revelations about Harley and The Joker’s past; and as Jack transforms into a hero of the middle class and takes extreme measures to mobilize a revolutionary army of super-villains, Bruce struggles to stay focused on engineering a technological breakthrough to save Alfred.

Tragedy strikes, and the Bat-family face the fight of their lives against an army of super-villains and waning public support. A new discovery reinforces Jack’s plot to jeopardize the Dark Knight’s standing in Gotham City, and Harley’s obsession with The Joker reaches a new height—and threatens to change the game for good!

Jim Gordon and the GCPD are thrown into disarray when Jack Napier leads a show stopping campaign to become councilman of the politically abandoned neighborhood of Backport. Civic backlash brews as Mayor Hill struggles to find creative ways of criminalizing Napier’s democratic aspirations, and Batman’s interference blooms into a liability for the GCPD’s public image. Through it all, the new Joker plots to derail everything—and new secrets about Harley’s past are revealed.

Jack’s mind and body begin to betray him as he prepares for an inevitable showdown with Batman, and Bruce himself struggles to keep his team united. As the game gets tougher, Batman seeks counsel from a shocking source—and after Wayne Manor is infiltrated, a car chase for the ages aims to curb Napier’s supercriminal crew once and for all.

Gotham City’s strongest alliance comes to an end when Gordon’s trust in Batman reaches its limit. On the verge of resignation, the commissioner attempts a final act of public service, but an unlikely intervention allows the Dark Knight to fight another day. Meanwhile, Jack’s mission takes a hit when his pills lose effect—and under cover of all this chaos, Neo Joker is positioned to take the city hostage.

This issue, it’s Jack versus the Joker! Napier’s identity crisis spins out of control and compromises his grand plans for Gotham City—but not before he strikes a fateful bargain with Neo Joker. A browbeaten Batman accepts a peace offering from Batgirl, and some unexpected advice from Alfred sets the tone for the GTO’s new mission to redeem the city.

In the extra-sized finale of Sean Murphy’s top-selling miniseries, Jack Napier’s suspicious seduction of Gotham City comes to its twisted conclusion! With the city on the verge of becoming an icy tomb for the GTO, Batgirl makes a crucial assist and Gordon is forced to reevaluate his judgment of Batman to secure the greater good. As the true Joker’s return becomes imminent, Harley seeks vengeance and reckons with the bleak future that looms for her loved ones.
